Furnace Ignitors & Hot Surface Ignitors

The ignitor lights the burner at the start of the heating cycle, either through direct hot-surface ignition or in combination with a pilot flame. Because ignitors are a common wear component, they are one of the most frequently replaced furnace parts.

Furnace Part Source carries a range of hot surface ignitors and related components for residential and light-commercial gas furnaces, boilers, and water heaters.

Common Ignitor Types We Carry

Common ignitor types include:

  • Silicon carbide hot surface ignitors used widely across many furnace brands.
  • Silicon nitride hot surface ignitors valued for durability and faster warm-up.
  • Ignitor and bracket assemblies that include the mounting hardware.
  • Universal replacement ignitors designed to fit multiple OEM part numbers.

How to Find the Right Ignitor

Before ordering, check the equipment data plate and the existing ignitor for the model number, voltage, and part number. Confirm the mounting hole pattern and bracket style, since ignitors can vary in shape even when voltage is the same.

For best fit, compare:

  • Original ignitor part number
  • Voltage, typically 120V or 240V
  • Mounting hole spacing and bracket style
  • Equipment model and serial number

Hot surface ignitors are fragile and should be handled carefully; avoid touching the ceramic element with bare hands, since oils can shorten its lifespan.

Ignitors From Leading HVAC Brands

Our catalog includes ignitors compatible with major furnace, boiler, and water heater brands, including both OEM and cross-reference universal replacement options.

Need Help Matching an Ignitor?

Not sure which ignitor you need? Use the model number, serial number, and part number from your unit to narrow the search, or contact Furnace Part Source for help identifying the correct replacement.

Ignitor FAQs

What are signs of a failing furnace ignitor?

Common signs include the furnace failing to light, repeated ignition lockouts, or a visibly cracked or discolored ignitor element.

Can I touch a new hot surface ignitor during installation?

Avoid touching the ceramic element directly with bare hands, since skin oils can create hot spots and shorten the ignitor's lifespan. Handle it by the base or use gloves.

Are universal ignitors compatible with my furnace?

Many universal ignitors are designed to cross-reference several OEM part numbers. Confirm voltage and mounting hole pattern before ordering a universal replacement.

What is the difference between silicon carbide and silicon nitride ignitors?

Silicon carbide ignitors are widely used and cost-effective, while silicon nitride ignitors typically offer faster warm-up and longer service life, though at a higher price point.
